Inter-access terminal unblocking and enhanced contention for co-existence on a shared communication medium

Abstract

Techniques for managing access to a shared communication medium are disclosed. Scheduling grants may be sent to different access terminals for different sets of resources for uplink transmission on the communication medium. A series of re-contention gaps may be scheduled for access terminal contention within or between the different sets of resources. Uplink and downlink transmission on the communication medium may be silenced during each of the series of re-contention gaps. Moreover, an access terminal may receive a scheduling grant that allocates a set of resources to the access terminal for uplink transmission on a communication medium and contend for access to the communication medium based on the scheduling grant. The access terminal may then selectively transmit uplink traffic over the allocated set of resources based on the contending.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the benefit of U.S. Provisional Application No. 62 / 212,096, entitled “Inter-Access Terminal Unblocking for Co-Existence on a Shared Communication Medium,” filed Aug. 31, 2015, and U.S. Provisional Application No. 62 / 212,344, entitled “Enhanced Contention Modes for Co-Existence on a Shared Communication Medium,” filed Aug. 31, 2015, each assigned to the assignee hereof and expressly incorporated herein by reference in its entirety.INTRODUCTION[0002]Aspects of this disclosure relate generally to telecommunications, and more particularly to operations on a shared communication medium and the like.[0003]Wireless communication systems are widely deployed to provide various types of communication content, such as voice, data, multimedia, and so on. Typical wireless communication systems are multiple-access systems capable of supporting communication with multiple users by sharing available system resources (e.g., ...

Benefits of technology

[0015]In another example, another communication method is disclosed. The method may include, for example, scheduling a plurality of access terminals for transmission on a communication medium; setting one or more contention parameters for an access point to contend for access to the communication medium based on the number of access terminals being scheduled; and contending for access to the communication medium by the access point in accordance with the one or more contention parameters.

[0016]In another example, another communication apparatus is disclosed. The apparatus may include, for example, at least one transceiver, at least one processor, and at least one memory coupled to the at least one processor. The at least one processor and the at least one memory may be configured to schedule a plurality of access terminals for transmission on a communication medium, and set one or more contention parameters for an access point to contend for access to the communication medium based on the number of access terminals being scheduled. The at least one transceiver may be configured to contend for access to the communication medium by the access...
